22⋅102=c2

Rewrite the equation as c2=22⋅102.

c2=22⋅102

Take the square root of both sides of the equation to eliminate the exponent on the left side.

c=±22⋅102

Simplify the right side of the equation.

Raise 2 to the power of 2.

c=±4⋅102

Raise 10 to the power of 2.

c=±4⋅100

Multiply 4 by 100.

c=±400

Rewrite 400 as 202.

c=±202

Pull terms out from under the radical, assuming positive real numbers.

c=±20

c=±20

The complete solution is the result of both the positive and negative portions of the solution.

First, use the positive value of the ± to find the first solution.

c=20

Next, use the negative value of the ± to find the second solution.

c=-20

The complete solution is the result of both the positive and negative portions of the solution.

c=20,-20

c=20,-20

c=20,-20

Solve for c 2^2*10^2=c^2
